PROBLEM TO BE SOLVED: To secure rigidity of a seat back and achieve sufficient weight reduction.SOLUTION: A seat back structure has: a seat back panel 10; a cushioning material 80; and an intermediate member 70 disposed between the seat back panel 10 and the cushioning material 80. The seat back panel 10 is formed by a metal plate material and provided with embossment parts 50 protruding toward a seating surface side (an intermediate member 70 side) and bead parts 51, each of which encloses the embossment part 50. The intermediate member 70 has specific gravity smaller than that of the cushioning material 80 and hardness which is set larger than that of the cushioning material 80. The intermediate member 70 is formed with contact parts 71 which respectively contact with the embossment parts 50, and recessed parts 72 formed at positions corresponding to the bead parts 51. Spaces K are formed around each contact part 71 between the intermediate member 70 and the seat back panel 10.SELECTED DRAWING: Figure 13

    【課題】シートバックを剛性を確保しつつ十分に軽量化する。【解決手段】シートバックパネル10と、クッション材80と、シートバックパネル10とクッション材80との間に配設される中間部材70と、を有する。シートバックパネル10は、金属製の板材により構成されて、その着座面側(中間部材70側)に向けて突出するエンボス部50が形成されると共に、エンボス部50を取り巻くようにビード部51が形成される。中間部材70は、比重がクッション材80よりも小さくかつ硬度がクッション材80よりも大きく設定される。中間部材70は、エンボス部50に当接する当接部71と、ビード部51に対応した位置において凹部72が形成されて、当接部50の周囲においてシートバックパネル10との間に空間Kが形成される。【選択図】 図13
